I was Skeptical About spending such a large amount of money on mudflaps but these really are the best of the best. Totally worth the investment the videos online or extremely helpful. Installation was easy.  Couldn’t be happier.  I went with the bigger ones and definitely recommend the mounting plate.

Question:
Answer:
Yes, the brackets are highly recommend. Mounting the flaps directly to the lip of the fender and the wheel well liner does not offer enough support and the flap will eventually pull off of the truck. Each dually flap weights almost 12lbs and the extra support is needed.
